They're often called "repeaters" which is actually a more accurate
description. Yes, they are used to get over the length limitation (you can
have up to 5 segments, connected by 4 repeaters, between any two hosts,
though not all segents can be populated and there are rules about lengths,
propagation delays, etc). They're also used to get over the
number-of-hosts-on-a-segment limitation.
However, they don't isolate collision domains; a collision on one segment
will be faithfully copied to the others.
